אם יש לך רשות להשתמש במחשב הזה, תכתבי את הסיסמה ותתחברי.

In unpointed Hebrew, לך can mean to you for either one male or one female.

The difference is in pronunciation:

• to a man: lecha
• to a woman: lach

Since normal modern Hebrew writing usually leaves out vowel marks, both are written לך.

We know this sentence is addressed to a woman because the verbs are feminine singular:

• תכתבי = you will write / write! (to one woman)
• תתחברי = you will log in / log in! (to one woman)

So here לך should be understood as lach.

Hebrew very often expresses possession with יש ל..., literally there is to....

So:

• יש לי ספר = I have a book
• יש לך רשות = you have permission

Literally, יש לך רשות means there is permission to you.

This is a very normal Hebrew structure. Hebrew does not usually use a separate everyday verb meaning to have the way English does.

רשות means permission.

להשתמש means to use.

So רשות להשתמש is literally permission to use.

The structure is very similar to English:

• permission to enter
• permission to speak
• permission to use

In Hebrew:

• רשות להיכנס
• רשות לדבר
• רשות להשתמש

The verb להשתמש normally takes the preposition ב־.

So Hebrew says:

• להשתמש במשהו = to use something

Literally, this can feel a bit like to make use of something.

Examples:

• להשתמש בעט = to use a pen
• להשתמש בטלפון = to use the phone
• להשתמש במחשב = to use a computer / the computer

So the ב is not optional here; it belongs with the verb.

In Hebrew, demonstratives like this usually come after the noun:

• הספר הזה = this book
• המחשב הזה = this computer

So במחשב הזה means in/on/with this computer, depending on context. Here it means use this computer.

Also, when a noun has this, it is definite, so Hebrew normally has the on the noun too. Underneath, the phrase is basically:

• ב + המחשב הזה

But when ב־ attaches to ה־, the spelling combines them, so you see במחשב rather than a separate ב המחשב.

Because the speaker is addressing one female person.

In Hebrew, verbs often show the gender and number of the person being addressed.

Here:

• תכתבי = write / you will write (to one woman)
• תתחברי = log in / you will log in (to one woman)

Compare:

• to one man: תכתוב, תתחבר
• to one woman: תכתבי, תתחברי
• to more than one person: תכתבו, תתחברו

So these endings tell you exactly who the command is aimed at.

This is very common in Modern Hebrew.

Forms like תכתבי and תתחברי are formally future-tense forms, but in everyday Hebrew they are also often used for commands, instructions, or requests.

So:

• תכתבי את הסיסמה can mean you will write the password, but in context it means write the password
• תתחברי can mean you will log in, but here it means log in

Hebrew does have true imperative forms:

• כתבי
• התחברי

But in everyday speech, the future forms are often more common and natural, especially in instructions.

את here is the direct object marker. It does not mean you in this sentence.

Hebrew uses את before a definite direct object.

So:

• אני רואה כלב = I see a dog
• אני רואה את הכלב = I see the dog

In your sentence:

• תכתבי את הסיסמה = write the password

Because הסיסמה is definite, it needs את.

This את usually has no separate English translation.

הסיסמה means the password.

The speaker is referring to a specific password — the one needed in this situation. So Hebrew uses the definite article ה־.

If you said just סיסמה, it would sound more like a password or some password, which is probably not the intended meaning here.

In context, תכתבי את הסיסמה means something like:

• enter the password
• write the password

English might sometimes say your password, but Hebrew often simply uses the password when the reference is clear.

ותתחברי comes from להתחבר.

The basic idea of להתחבר is to connect or to connect oneself. In technology/computer contexts, it often means:

• to log in
• to sign in
• to connect

So ותתחברי here means and log in or and then log in.

The ו־ at the beginning means and. In this sentence it links the two actions:

• תכתבי את הסיסמה = write/enter the password
• ותתחברי = and log in

So the sequence is: enter the password and log in.
